Effects of nano/microplastic exposure on zebrafish (Danio rerio) gut microbiome

EF 2024-25 · 2024-09-01

Résumé
Plastic pollution is a worldwide problem. As plastic pollution is expected to grow, the amount of plastic in the environment is also expected to grow. Plastic pieces found in the environment are categorized depending on their size: microplastics (MP) (1-5000 µm) and nanoplastics (NP) (1-1000 nm). Both micro and nanoplastics can have deleterious effects when ingested by organisms in the environment. Observed effects varies from food dilution, oxidative stress and lower reproductive success. Additionally, more and more research is done on organisms microbiome. Once ingested, microplastics are mainly accumulating in the gastro-intestinal tract before being egested with feces and only a small portion will reach other organs. In the case of nanoplastics, due to their small sizes, they can cross biological barriers and can be distributed within all organs. As the gastro-intestinal tract is where both micro and nanoplastic transit through, these particles can have potential effects on the gastro-intestinal tract itself but also on the microbiome inhabitating it. Additionally, some research found that nanoplastics can disrupt the brain-intestine-microbiota axis, and call for this endpoint to be studied when assessing the environmental risk of micro and nanoplastics. To study the effects of micro and nanoplastics on gut microbiota, we propose to use adult zebrafish (Danio rerio) as a model species.

Description (French)
La pollution plastique est un problème mondial. On s’attend à ce que cette pollution augmente, de même que la quantité de plastique dans l’environnement. Les morceaux de plastique trouvés dans l’environnement sont classés en fonction de leur taille : les microplastiques (MP) (1-5000 µm) et les nanoplastiques (NP) (1-1000 nm). Les microplastiques et les nanoplastiques peuvent avoir des effets néfastes lorsqu’ils sont ingérés par les organismes présents dans l’environnement. Parmi ceux-ci, on note la dilution de la nourriture au stress oxydatif, en passant par une baisse du taux de reproduction. En outre, le microbiome des organismes fait l’objet d’un nombre croissant de travaux de recherche. Une fois ingérés, les microplastiques s’accumulent principalement dans le tractus gastro-intestinal avant d’être évacués avec les matières fécales et seule une petite partie atteindra d’autres organes. En raison de leur petite taille, les nanoplastiques peuvent traverser les barrières biologiques et se répartir dans tous les organes. Le tractus gastro-intestinal étant le lieu de passage des micro/nanoplastiques, ces particules peuvent avoir des effets potentiels sur le tractus gastro-intestinal lui-même, mais aussi sur le microbiome qui l’habite. En outre, certaines recherches ont montré que les nanoplastiques peuvent perturber l’axe cerveau-intestin-microbiote, et demandent que ce paramètre soit étudié lors de l’évaluation du risque environnemental des micro/nanoplastiques. Pour étudier les effets des micro/nanoplastiques sur le microbiote intestinal, nous proposons d’utiliser le poisson zèbre adulte (Danio rerio) comme espèce modèle.
